Smart tags with multiple interactions

ABSTRACT

A method for Near Field Communication (NFC) based interactions can be implemented by a device when it is placed near an NFC tag and receives an electromagnetic signal associated with the NFC tag. The device retrieves the identifier of the NFC tag from the electromagnetic signal and, based on the identifier, the device can generate a first command. Furthermore, the device can identify a qualifying event, such as a predetermined orientation of the device. The device then generates a second command in response to the identification of the qualifying event. Each of the first and second command can cause a change in settings of the device, switching an operating mode of the device, activating/deactivating an application, enabling/disabling a feature of an application, and sending an instruction to a remote electronic device.

BACKGROUND Technical Field

This disclosure generally relates to interactions of Near Field Communication (NFC) tags with devices (e.g., mobile devices). More particularly, this disclosure relates to devices and method for NFC-based interactions that involve generating one or more commands by the devices based on detecting one or more NFC tags by the devices and determining one or more qualifying events by the devices.

Description of Related Art

The use of NFC tags, such as those that interact with smartphones, have become common in many aspects of human life as they enhance the functionality of a device (e.g., a mobile device). For example, NFC tags can be used to gain access to a building, grant an entitlement, direct a user to a website, make a payment, open an application, etc. An NFC tag is typically write protected and includes unique information that determines the action performed when a mobile device or reader interacts with the tag. Devices will typically read an NFC tag once and perform one action, limiting the functionality of the NFC tag. In addition, NFC chips are being built into an increasing number of devices and can also be implanted into individuals. Thus, improvements to interactions with NFC tags and NFC chips are needed.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS

The present disclosure generally relates to systems and methods for providing or improving interaction with a device based on NFC tags. NFC tags can be also referred to as “smart tags” or Radio-Frequency Identification (RFID) tags, and the like. NFC tags can be implemented as stickers, key fobs, or in any other similar manner so that they can be fixed, mounted, connected, or otherwise coupled to certain items indoors or outdoors. For example, NFC stickers can be placed near a bed, on a kitchen table, door, inside vehicle, and the like. A device includes mobile devices, and an application includes mobile applications.

To interact with NFC tags, a user can use a device, such as a smartphone, which has a NFC communication module configured to wirelessly communicate with one or more NFC tags when the device is in a vicinity of NFC tags (e.g., at a distance less than about 2 inches). Each NFC tag can be uniquely identified as it bears a unique identifier. When the device reads an electromagnetic signal generated by the NFC tag, the device can detect or retrieve the unique identifier of the NFC tag. Furthermore, as a response to the identification of the unique identifier of the NFC tag, the device can perform pre-programmed operations associated with the unique identifier. The pre-programmed operations can cause a change in settings of the device, cause switching between operating modes of the device, cause activating/deactivating of an application, cause enabling/disabling a feature of the application, or cause sending an instruction to a remote electronic device. For example, placing the device in a vicinity of one of the NFC tags coupled to a couch, could activate a remote control application on the device to enable a remote control application to control a television (TV) device by the user. In another example, placing the device close to another NFC tag attached to a refrigerator can activate a tracking feature of the device or application to track amount of water that the user drinks.

Each NFC tag includes a passively emitting device not requiring electrical power as it emits signals in response to a wireless signal received from the device. In some example embodiments, the longest side of the NFC tag can be, optionally, of about one inch or less. NFC tags can be of different colors such as white, black, red, blue, green, yellow, metallic, transparent, and so forth. Furthermore, each tag can include a chip and a communication module having a coil or an antenna. The chip can be configured to cause the communication module to emit a certain electromagnetic signal bearing a unique identifier of an NFC tag, for example, as a response to a received signal from a device. Each NFC tag can include an adhesive layer so that it can be used as a sticker. Moreover, users can secure NFC tags with magnets, pins, or clips so that they can be easily transportable from one location to another.

The device can be programmed before it can interact with NFC tags. To these ends, after placing the NFC tag at a desired location, the user can open a certain application and place the device near the NFC tag. The user would need to pre-program and indicate what actions or operations the device is to perform upon sensing the electromagnetic signal bearing the unique identifier of the NFC tag. For example, the user can set up IFTTT (If This Then That) commands to be executed upon sensing the electromagnetic signal bearing the unique identifier of the NFC tag. The user can also set up the device such that the presence of the NFC tag would open and perform actions by one or more specific applications of the device. Moreover, two or more actions can be available for every NFC tag. For example, a first action can initiate with a tap or placement of the device in a vicinity of an NFC tag. The device can send a notification such as a vibrational notification when the first action is successfully initiated or completed or about to be initiated.

Furthermore, upon detection of certain qualifying event, a second action can be initiated by the device. For instance, if the user holds the device over the NFC tag after the first notification for a predetermined period, the first action can be suppressed and the second action can be initiated instead of the first action. In this case, the device can notify the user with a second notification such as a double vibration. Confirmations (vibrations or audible beeps) can be enabled or disabled for each NFC tag individually. After the NFC tag is registered with the user's device, the user can move the NFC tag and/or set it to perform other operations without the need to re-register the NFC tag with the device. In some embodiments, the users can also initiate actions directly on the application for all of their registered NFC tags.

The following describes some example scenarios of using NFC tags to cause implementations of certain predetermined actions by a device. In one example, an NFC tag can be added to a magnet to be placed on a refrigerator. When a user taps a device on the NFC tag, it causes a fitness tracking application or nutrition tracking application to add up a cup of water to a user's account. However, if the user holds the device near the NFC tag for a predetermined period, the device causes the opening of a food tracking form of the nutritional application instead of adding a cup of water. In another example, an NFC tag can be added to a pin to be placed on a shirt of a user such that when the user places his mobile device close to the NFC tag, it causes the opening of a favorite mobile game or another application.

In an alternative embodiment, when the NFC tag is placed on a couch, the device can open a remote control application if the device comes into close contact with the NFC tag. In yet additional example, a NFC tag can be glued to a clip. The clip can be attached to food packaging such as a snack box. When the user taps the mobile device over the NFC tag, the device can automatically record the number of snacks the user eats. If the NFC tag is placed inside a car, the application can automatically cause opening a garage door when the device comes into a close proximity of the NFC tag.

According to some embodiments, there can be some additional ways to interact with NFC tags, which can cause implementation of one or more actions upon detecting NFC tags by a device and upon identifying one of a plurality of qualifying events. The qualifying events can be as follows: a device taps a NFC tag (e.g., a brief touch of the NFC tag by the device), an orientation of the device (e.g., upside down), a state of the device (e.g., locked or unlocked), a period of holding the device close to the NFC tag, a geographical location of the device (e.g., it can be determined if the device is close to a predetermined location or item).

FIG. 1 shows a block diagram illustrating a system 100 for providing NFC-based interactions according to one example embodiment. System 100 includes a device 105, such as a smart phone, which can interact with one or more NFC tags 110. Each NFC tag 110 can include at least a chip 115, such as a microcontroller, microprocessor, circuit, logic, and the like. Each NFC tag 110 can also include a communication module 120 including, for example, an antenna or coil. The NFC tag 110 may also not include the communication module 120. If the NFC tag 110 does contain the communication module 120, the communication module 120 can be configured to receive a first electromagnetic signal originated from device 105 (e.g., a signal to power NFC tag 110 and request a response). Communication module 120 can be also configured to transmit or emit a second electromagnetic signal for further reception by device 105. The second electromagnetic signal can be generated as a response to the first electromagnetic signal. The second electromagnetic signal can include a unique identifier of NFC tag 110 and, optionally, other information such as predetermined commands, instructions, location information, and so forth. The elements of NFC tag 110, including chip 115 and communication module 120, can be arranged in a housing or substrate 125. Substrate 125 can be rigid or flexible. Each of NFC tags 110 can be also equipped with an adhesive layer 130 attached to an external side of housing or substrate 125. NFC tags 110 can be of any desired color and shape. For example, NFC tags 110 can be implemented as stickers or key fobs. NFC tags 110 can be placed, mounted, fixed, glued, attached, pinned, or otherwise connected to various items indoors or outdoors. For example, NFC tags 110 can be attached to apparel, furniture, vehicle, computer, building elements, and so forth.

Device 105 includes at least a NFC communication module 135, a processor 140, and a memory 145 for storing processor-executable instructions. Other elements of device 105 shall be evident from FIG. 3 and its respective description which follows. NFC communication module 135 is configured to communicate with NFC tag 110 for, at least, receiving the second electromagnetic signal. Communication between NFC communication module 135 and NFC tag 110 can be successful only when NFC tag 110 is within a predetermined distance from NFC communication module 135, such as, less than ten inches, preferably less than two inches. NFC communication module 135 can also generate the first electromagnetic signal and emit it for further receipt by NFC tags 110. Upon receipt of the second electromagnetic signal by device 105, the second electromagnetic signal can be processed by processor 140 to retrieve the unique identifier of NFC tag 110. Further, processor 140 can execute processor-executable instructions stored in memory 145 to cause implementation of one or more predetermined or preprogrammed actions associated with the unique identifier as a response to receipt of the second electromagnetic signal.

Processor 140 can also identify one or more identifying events, such as a period of presence of device 105 near a particular NFC tag 110, determination of a current geographical location of device 105, determination of a current orientation of device 105, determination of a current status of device 105 (e.g., if it is locked or unlocked), and so forth. The determination of geographical location of device 105 can be implemented with the help of a Global Positioning System (GPS) module or another common device for determining a geographical location, which can be installed in device 105. The determination of current orientation of device 105 can be determined with the help of inertial sensors, gyroscopes, or motion sensors, which can be installed in device 105. Determination of a period indicating how long device 105 is located near a particular NFC tag 110 can be executed with the help of a clock, which can be installed in device 105.

As indicated above, device 105 can execute one or more actions as response to detection of NFC tag 110 or detection of one of qualifying event. Some examples of these “actions” include, but not limited to, causation of changing a setting of the device, causation of switching an operating mode of the device, causation of activating/deactivating the application, causation of enabling/disabling a feature of the application, and the like. In some embodiments, an action can be a causation of sending a predetermined instruction to one or more remote electronic devices 150. The instruction can be sent via a communications network 155. Communications network 155 can refer to any wired, wireless, or optical networks including, for example, the Internet, intranet, local area network (LAN), Personal Area Network (PAN), Wide Area Network (WAN), Virtual Private Network (VPN), cellular phone networks (e.g., packet switching communications network, circuit switching communications network), Bluetooth radio, Ethernet network, an IEEE 802.11-based radio frequency network, IP communications network, or any other data communication network utilizing physical layers, link layer capability, or network layer to carry data packets, or any combinations of the above-listed data networks.

FIG. 2 is a process flow diagram showing a method 200 for NFC-based interaction according to an example embodiment. Method 200 may be performed by processing logic that may comprise hardware (e.g., decision-making logic, dedicated logic, programmable logic, application-specific integrated circuit (ASIC)), software (such as software run on a general-purpose computer system or a dedicated machine), or a combination of both. In one example embodiment, the processing logic refers to one or more elements of device 105 of FIG. 1. Below recited operations of method 200 may be implemented in an order different than described and shown in the figure. Moreover, method 200 may have additional operations not shown herein, but which can be evident for those skilled in the art from the present disclosure. Method 200 may also have fewer operations than outlined below and shown in FIG. 2.

At operation 205, device 105 receives an electromagnetic signal of NFC tag 110 when device 105 is within a first predetermined distance from the NFC tag (e.g., less than two inches). The electromagnetic signal of NFC tag 110 can be received in response to another electromagnetic signal generated by device 105.

At operation 210, device 105 retrieves an identifier of NFC tag 110 from the electromagnetic signal received at operation 205. The identifier can uniquely identify NFC tag 110. Device 105 can include one or more settings associated with the identifier of NFC tag 110.

At operation 215, device 105 generates a first command based on the identifier. The first command is configured to cause performing one or more of the following: change at least one setting of device 105, switch at least one of operating modes of device 105, activate at least one of the applications of device 105, deactivate at least one of the applications of device 105, enable at least one feature of at least one of the applications of device 105, disable at least one feature of at least one of the applications of device 105, and send a first instruction to at least one of remote electronic devices 150. Further, at operation 215, device 105 can generate a first notification (such as an audio alert, displayable message, or vibration alert) and deliver it to the user prior to or after the generation of first command.

At operation 220, device 105 identifies a qualifying event before or after the first command is generated. In some embodiments, the identification of the qualifying event can include determining, by device 105, that device 105 is located within the first predetermined distance from NFC tag 110 for a predetermined period (e.g., 1, 2, 3, 4, 5 or more seconds). In some embodiments, the identification of the qualifying event can include determining, by device 105, that device 105 is orientated substantially upside down such that a display of device 105 is substantially parallel to and faces the ground. In some embodiments, the identification of the qualifying event can include determining, by device 105, that device 105 is locked. In some embodiments, the identification of the qualifying event can include determining, by device 105, that device 105 unlocked. In some embodiments, the identification of the qualifying event can include determining, by device 105, that device 105 is located within a second predetermined distance (e.g., less than 5 feet) from a predetermined geographical location associated with the identifier of NFC tag 110. This predetermined geographical location associated with the identifier can be, for example, a garage door, piece of furniture, a particular room or office in a building, outdoor location, vehicle, and so forth.

At operation 225, device 105 generates a second command based on the identification of the qualifying event. In one embodiment, the second command is generated after the first command is generated. In another embodiment, the second command is generated and the first command is suppressed upon identification of the qualifying event. The second command can be configured to cause performing one or more of the following: change at least one setting of device 105, switch at least one of operating modes of device 105, activate at least one of the applications of device 105, deactivate at least one of the applications of device 105, enable at least one feature of at least one of the applications of device 105, disable at least one feature of at least one of the applications of device 105, authenticate the identity of an individual, enable at least one or more additional immersive interactions with the at least one application, and send a second instruction to at least one of remote electronic devices 150. Further, at operation 225, device 105 can generate a second notification (such as an audio alert, displayable message, or a double vibration notification) and deliver it to the user prior to or after the generation of second command.

FIG. 3 is a high-level block diagram illustrating a computing device 300 suitable for implementing the methods described herein. In particular, computing device 300 may be used for implementing the methods for NFC-based interaction as described above. Computing device 300 may include, be, or be an integral part of one or more of a variety of types of devices, such as a mobile device, among others. In some embodiments, computing device 300 can be regarded as an instance of device 105.

As shown in FIG. 3, computing device 300 includes one or more processors 310, memory 320, one or more mass storage devices 330, one or more output devices 350, one or more input devices 360, one or more network interfaces 370, one or more optional peripheral devices 380, and a communication bus 390 for operatively interconnecting the above-listed elements. Processor(s) 310 can be configured to implement functionality and/or process instructions for execution within computing device 300. For example, processor(s) 310 may process instructions stored in memory 320 or instructions stored on mass storage devices 330. Such instructions may include components of an operating system or software applications.

Memory 320, according to one example, is configured to store information within computing device 300 during operation. For example, memory 320 can store settings or pre-programmed commands associated with one or more NFC tags 110. Memory 320, in some example embodiments, may refer to a non-transitory computer-readable storage medium or a computer-readable storage device. In some examples, memory 320 is a temporary memory, meaning that a primary purpose of memory 320 may not be long-term storage. Memory 320 may also refer to a volatile memory, meaning that memory 320 does not maintain stored contents when memory 320 is not receiving power. Examples of volatile memories include RAM, dynamic random access memories (DRAM), static random access memories (SRAM), and other forms of volatile memories known in the art. In some examples, memory 320 is used to store program instructions for execution by processor(s) 310. Memory 320, in one example, is used by software applications or mobile applications. Generally, software or mobile applications refer to software applications suitable for implementing at least some operations of the methods as described herein.

Mass storage devices 330 can also include one or more transitory or non-transitory computer-readable storage media or computer-readable storage devices. For example, memory 320 can store instructions for processor(s) 310, settings or pre-programmed commands associated with one or more NFC tags 110. In some embodiments, mass storage devices 330 may be configured to store greater amounts of information than memory 320.
